The character of Kristin first appeared on Dallas during the second season in the company of her mother, Patricia Shepard (Martha Scott).

Patricia was always proud that her daughter, former beauty pageant winner Sue Ellen (Linda Gray), had married into the prominent Ewing family.

Patricia was hoping her younger daughter Kristin (then portrayed by Colleen Camp) would also find a successful man to marry.

[2] Early in the fourth season, Sue Ellen (falsely accused of shooting J.R.) realized that her sister Kristin had shot J.R. and the truth came out in a poolside conversation between the three of them.

Instead of pressing charges against Kristin for the shooting, J.R. sent her packing out of town and agreed to send her a monthly check for living expenses.

Kristin then married petty criminal Jeff Farraday (who was the same blood type as J.R.) and gave birth to Christopher.

She contacted Valene Ewing in an attempt to get out of jail and is invited to stay with Val and Gary, who is not happy to see her there knowing fully that Kristin was far more conniving than Sue Ellen, while she gets back on her feet.

Kristin tried to form a relationship with the Ewings' neighbor Kenny Ward, who was separated from his wife Ginger at the time.

Kristin came clean and admitted that she was pregnant to Val and Gary, and said that she only tried to seduce Kenny in order to give her baby a father.
